TENDER FOR TRACTION-ENGINES.

SPECIFICATION forming part of Letters Patent No. 739,703, dated September 22, 1903. Application filed March 80, 1903; Serial No. 150,209- (No model.)

To all wig/m tom/00y concern:

Be it known that I, GEORGE M. NELLANS', a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Two-Wheeled 'Water- Tenders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improved two-wheeled water-tender adapted to be attached to a traction-engine between the latter and the grainseparator or other machine drawn or operated by the tractionlengine and which is designed to keep in line with the engine when it is moving backward or forward; and it consists in the peculiar construction and combination of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of the frame of a water-tender embodying this invention, showing the same connected to a traction-engine, the latter being indicated diagrammatically. Fig. 2 is a vertical transverse sectional'view of v the frame of the water-tender, taken on the plane indicated by the line at a of Fig. 1. Fig. 3 is a vertical longitudinals'ectional view of the same,take'n' onthe plane indicated by the line b b of Fig. 1. Figs. 4 and 5 are detail elevations of the cap-pieces and the pivotallymounted wheel-supporting elements.

In the embodiment of the present invention cap-pieces 1 are provided,which are connected together by cross-bars 2; The latter are disposed one above the other. Intermediate the cap-pieces are wheel-supporting elements 3, which are independently mounted for horizontal angular movement between the said cap-pieces. Each of the said wheel-supporting elements is here shown as a block 4, having an outwardly-extending spindle 5 for a supporting-wheel 6 and an inwardly-extending arm 7, forming a lever by which the block may be turned between the cap-pieces. In

the present embodiment of the inventioil the block 4 and cap-pieces are provided with coengaging cylindrical recesses and shoulders, as at 8, at their opposing sides, in which are circular ball-races and bearing-balls 10, the same forming antifriction-bearings between the blocks 4 and the cap-pieces. In the present' embodiment of the invention the respective cap-pieces and blocks 4 are connected together by centrally and vertically disposedv bars 2, and the end portions thereof are connected to caps 1 by side brace-bars 15, as shown. These brace-bars are in practice preferably made of angle iron or steel, and their intermediate portions are connected together by curved brace-bars 16, the latter being also connected to the upper and lower cross-bars 2, as shown. The inner ends of the arms 7 of the wheel-supporting elements operate between the intermediate braces 16, the latter being concentric with the pivotal axis of the wheel-supporting elements.

The draw-bar 14: is provided near its ends with directionelements,which are here shown as sheaves 17. The latter are connected to gether by a flexible connecting element 18,

respective spindles 5 to be always maintained in parallel relation to keep the tender in line with the traction-engine to which it is coupled, both when the engine is moving in a straight course and when the same is describing a curve.

In Fig. 1 the traction-engine is indicated at A diagrammatically,and its pivotal axle B is shown as connected by operating-cords or the like elements to the inner ends of the arms-7.

Hence the wheel-supporting elements of the tender-frame are turned automatically by a pivoted axle or truck of the traction-engine. It will be understood that one end of the draw-bar is coupled by any suitable means to the traction-engine. "When the latteris em- ICO is claimed is In a vehicle of the class described, aframe having a longitudinally-disposed draw-bar, cross-bars,above and below it and having cappieces at their ends, braces 15 connecting the ends of the cross-bars and the draw-bar,braces 16 connecting the intermediate portions of the said braces and cross-bars, direction elements carried by the draw-bar, wheel-supporting elements pivotally mounted between the cap-pieces at the sides of the frame for angular movement, and provided with inwardly-extending arms which operate between the braces 16, and a flexible element connecting the direction elements and having its respective leads connected to the said arms tomaintain the supporting-wheels in parallel relation, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- 35 nesses.
